[Embodiment 4]

50 and 51 are a perspective view of the upper surface side and a perspective view of the lower surface side of the cassette 510 of another embodiment of the present invention. As shown in FIG. 52, the cassette 510 of the present embodiment includes only the printing tape roll 526. Similar to the printing tape 422 of the third embodiment, the printing tape 522 of the printing tape roll 526 of the present embodiment has a release tape 522c as an adhesive on the surface of the tape to be printed 522a as a base material opposite to the printing surface. It is configured by being laminated via 522b. FIG. 53 shows the printed printing tape 522 sent out from the cassette 510. Similar to the printing tape 422 of the third embodiment shown in FIG. 34, the printing tape 522 of the present embodiment includes a printing tape 522a as a base material made of a heat-sensitive material that self-colors, for example, black when heated, and a printing tape 522a. It is composed of a release tape 522c laminated on the sticking surface of the above via an adhesive 522b. A local coloring region 522d formed by local heating is shown on a part of the tape to be printed 522a.

As shown in FIG. 52, the cassette 510 of the present embodiment includes the first case member 212, the second case member 214, the third case member 216, and the fourth case member 218 of the cassette 210 of FIG. 21 of the second embodiment. Although it is configured by using the first case member 512, the second case member 514, the third case member 516, and the fourth case member 518, which are similarly configured, the ink ribbon 268 is wound around the supply spool 270. It differs from the cassette 210 in that it does not include the ink ribbon roll 272 and the take-up spool 276 for winding the ink ribbon 268.

According to the cassette 510 of the present embodiment, the third case member 516 of the cassette 510 is the same as the concave wall 216c forming the first side wall 216a, the second side wall 216b, and the concave portion 299 of the third case member 216 of the cassette 210. Since the first side wall 516a, the second side wall 516b, and the recess wall 516c forming the recess 599 are provided, the same effect as that of the cassette 210 can be obtained.

It should be noted that the above description is merely a positional embodiment of the present invention, and the present invention can be modified in various ways without departing from the spirit of the present invention.

first case member

12, 212, 412, 512, the

second case member

14, 214, 414, 514, and the

third case member

16, 216, 416, 516. , And four

case members

18, 218, 416, and 516 are stacked in the vertical direction, but the cassette 10 is not limited to this configuration. For example, as shown in FIG. 54, the

cassettes

10, 210, 410, and 510 are the

first case members

12, 212, 416, 516, the fifth case member 501, and the

fourth case members

18, 218, 418, and 518. The case members may be laminated in the vertical direction. The fifth case member 501 has through holes 502 that penetrate vertically corresponding to the through

holes

52, 58 and the like of the above embodiment, and partitions the first space S1 and the second space S2. The upper surface side of the fifth case member 501 has the same shape as the upper surface side of the

second case members

14, 214, 414, 514, and the lower surface side is the lower surface side of the

third case members

16, 216, 416, 516. It should be configured in the same shape. In the case of this modification, the

first case member

12, 212, 414, 514 and the fifth case member 501 form a first case having the first space S1 inside, and the fifth case member 501 and the fourth case member A second case having a second space S2 inside is configured by 18, 218.

Further, in the above embodiment, the

recesses

99, 299, 499, and 599 show a shape surrounded by U-shaped recessed

walls

16c, 216c, 416c, and 516c, but the shape is not limited to this shape. For example, it may be a circular recess.

Further, the printing tape roll, the bonding tape roll, the ink ribbon roll and the take-up spool of the above-described embodiment are provided with their diameters horizontal with respect to the front-rear direction and the left-right direction, but these are provided horizontally. It does not have to be. For example, when the printing tape roll is not provided horizontally with respect to the front-rear direction and the left-right direction, the first direction, which is the width direction of the printing tape, is a direction different from the vertical direction of the above embodiment. In this case, the second direction orthogonal to the first direction, which is the width direction of the printing tape, and the third direction orthogonal to the first direction and the second direction are the front-back direction and the left-right direction of the above-described embodiment, respectively. It goes in a different direction.

Further, the arrangement of the printing tape roll, the bonding tape roll, the ink ribbon roll, and the take-up spool is not limited to the position shown in the above embodiment. For example, in the first embodiment, the bonding tape roll 64 may be arranged on the right side of the take-up spool 76, or the take-up spool 76 may be arranged on the front side of the ink ribbon roll 72.

Further, in the first embodiment, the recess 99, the bonding tape roll 64, the supply spool 70, and the take-up spool 76 are all arranged at positions where they overlap the printing tape roll 26 in the vertical direction, but the configuration is not limited to this. At least the recess 99 may be arranged at a position where it overlaps the printing tape roll 26 in the vertical direction. Similarly, in the second to fourth embodiments, at least the recesses may be arranged at positions where they overlap with the printing tape roll in the vertical direction. Further, in the above-described first to fourth embodiments, the concave portion or the concave wall overlaps the printing tape spool in the vertical direction, but at least the concave portion or the concave wall overlaps the printing tape wound around the printing tape spool in the vertical direction. Just do it.

Further, the printing tape rolls of the above-described embodiments 1 to 4 are configured by winding the printing tape around the printing tape spool which is a cylindrical shaft core material, but the printing tape is wound around the printing tape spool. Instead, the printing tape roll may be formed by winding around the first support protrusion and the second support protrusion. Similarly, the bonding tape 60 is wound around the bonding tape spool 62 without being wound, and the outer circumference of the bonding tape 60 is defined and arranged by the bonding tape roll holding wall 84 and the arcuate wall 92. You may.
